What 4th order wall design should I go with

[46panel]

Using 4 18" Incriminator Audio Death Penalty subs on 1 IA 40.1 at .5 ohm for a while. Was told that having the subs face each other it would have a lower bandwidth which is what I'm going for so I'm leaning towards doing that. This will be a daily driving ground pounder that I want to get low low, but still put up respectable numbers. The sealed section will be between 10-11 and ported about 20 cubes and the port is going to be tuned at 45hz

I edited this thread with what I am planning on going with. The pic below

You already got my input, port on driver´s side like the first sketch will give you a better score but you would have to demo and hairtrick with your window and door closed, depends on you, whatever you decide, i´m tuned in since i wanna steal your ideas for my wall

Yea I still think it'd do a hairtrick either way in either window But I am still leaning towards doing it in the middle since I'm not going for numbers
